impl f32x4

pub const fn new(array: [f32; 4]) -> Self

pub fn simd_eq<Rhs>(self, other: Rhs) -> <Self as CmpEq<Rhs>>::Output

where Self: CmpEq<Rhs>,

Test if each element is equal to the corresponding element in other.

pub fn simd_ne<Rhs>(self, other: Rhs) -> <Self as CmpNe<Rhs>>::Output

where Self: CmpNe<Rhs>,

Test if each element is not equal to the corresponding element in other.

where Self: CmpLt<Rhs>,

Test if each element is less than the corresponding element in other.

pub fn blend(self, t: Self, f: Self) -> Self

pub fn abs(self) -> Self

pub fn signum(self) -> Self

pub fn floor(self) -> Self

pub fn ceil(self) -> Self

pub fn fast_max(self, rhs: Self) -> Self

Calculates the lanewise maximum of both vectors. This is a faster implementation than max, but it doesn’t specify any behavior if NaNs are involved.

pub fn max(self, rhs: Self) -> Self

Calculates the lanewise maximum of both vectors. If either lane is NaN, the other lane gets chosen. Use fast_max for a faster implementation that doesn’t handle NaNs.

pub fn fast_min(self, rhs: Self) -> Self

Calculates the lanewise minimum of both vectors. This is a faster implementation than min, but it doesn’t specify any behavior if NaNs are involved.

pub fn min(self, rhs: Self) -> Self

Calculates the lanewise minimum of both vectors. If either lane is NaN, the other lane gets chosen. Use fast_min for a faster implementation that doesn’t handle NaNs.

pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval unless it is NaN.

If self is NaN, or min is NaN, or max is NaN, the result is NaN. If min > max, the result is min, since fast_max(min) dominates.

pub fn fast_clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval unless it is NaN.

Avoids NaN detection; same speed as the old clamp prior to IEEE 754-2019 compliance. Does not specify any behavior if NaNs are involved, and if min > max the result is unspecified.

pub fn midpoint(self, other: Self) -> Self

pub fn is_nan(self) -> Self

pub fn is_finite(self) -> Self

pub fn is_inf(self) -> Self

pub fn round(self) -> Self

pub fn fast_round_int(self) -> i32x4

Rounds each lane into an integer. This is a faster implementation than round_int, but it doesn’t handle out of range values or NaNs. For those values you get implementation defined behavior.

pub fn round_int(self) -> i32x4

Rounds each lane into an integer. This saturates out of range values and turns NaNs into 0. Use fast_round_int for a faster implementation that doesn’t handle out of range values or NaNs.

pub fn trunc(self) -> Self

pub fn fast_trunc_int(self) -> i32x4

Truncates each lane into an integer. This is a faster implementation than trunc_int, but it doesn’t handle out of range values or NaNs. For those values you get implementation defined behavior.

pub fn trunc_int(self) -> i32x4

Truncates each lane into an integer. This saturates out of range values and turns NaNs into 0. Use fast_trunc_int for a faster implementation that doesn’t handle out of range values or NaNs.

pub fn fract(self) -> Self

pub fn mul_add(self, m: Self, a: Self) -> Self

Performs a multiply-add operation: self * m + a

When hardware FMA support is available, this computes the result with a single rounding operation. Without FMA support, it falls back to separate multiply and add operations with two roundings.

Platform-specific behavior

• On x86/x86_64 with FMA: Uses vfmadd (single rounding, best accuracy)
• On ARM64 with NEON: Uses vfmaq_f32 (single rounding, best accuracy)
• Without FMA support: Uses (self * m) + a (two roundings)

Examples

let a = f32x4::from([1.0, 2.0, 3.0, 4.0]);
let b = f32x4::from([5.0, 6.0, 7.0, 8.0]);
let c = f32x4::from([9.0, 10.0, 11.0, 12.0]);

let result = a.mul_add(b, c);

let expected = f32x4::from([14.0, 22.0, 32.0, 44.0]);
assert_eq!(result, expected);

pub fn mul_sub(self, m: Self, s: Self) -> Self

Performs a multiply-subtract operation: self * m - s

When hardware FMA support is available, this computes the result with a single rounding operation. Without FMA support, it falls back to separate multiply and subtract operations with two roundings.

Platform-specific behavior

• On x86/x86_64 with FMA: Uses vfmsub (single rounding, best accuracy)
• On ARM64 with NEON: Uses vfmaq_f32(-s, self, m) (single rounding, best accuracy)
• Without FMA support: Uses (self * m) - s (two roundings)

Examples

let a = f32x4::from([10.0, 20.0, 30.0, 40.0]);
let b = f32x4::from([2.0, 3.0, 4.0, 5.0]);
let c = f32x4::from([5.0, 10.0, 15.0, 20.0]);

let result = a.mul_sub(b, c);

let expected = f32x4::from([15.0, 50.0, 105.0, 180.0]);
assert_eq!(result, expected);

pub fn mul_neg_add(self, m: Self, a: Self) -> Self

Performs a negative multiply-add operation: a - (self * m)

When hardware FMA support is available, this computes the result with a single rounding operation. Without FMA support, it falls back to separate operations with two roundings.

Platform-specific behavior

• On x86/x86_64 with FMA: Uses vfnmadd (single rounding, best accuracy)
• On ARM64 with NEON: Uses vfmsq_f32 (single rounding, best accuracy)
• Without FMA support: Uses a - (self * m) (two roundings)

Examples

let a = f32x4::from([3.0, 4.0, 5.0, 6.0]);
let b = f32x4::from([2.0, 2.0, 2.0, 2.0]);
let c = f32x4::from([10.0, 20.0, 30.0, 40.0]);

let result = a.mul_neg_add(b, c);

let expected = f32x4::from([4.0, 12.0, 20.0, 28.0]);
assert_eq!(result, expected);

pub fn mul_neg_sub(self, m: Self, s: Self) -> Self

Performs a negative multiply-subtract operation: -(self * m) - s

When hardware FMA support is available, this computes the result with a single rounding operation. Without FMA support, it falls back to separate operations with two roundings.

Platform-specific behavior

• On x86/x86_64 with FMA: Uses vfnmsub (single rounding, best accuracy)
• On ARM64 with NEON: Uses -(vfmaq_f32(s, self, m)) (single rounding, best accuracy)
• Without FMA support: Uses -(self * m) - s (two roundings)

Examples

let a = f32x4::from([3.0, 4.0, 5.0, 6.0]);
let b = f32x4::from([2.0, 2.0, 2.0, 2.0]);
let c = f32x4::from([1.0, 2.0, 3.0, 4.0]);

let result = a.mul_neg_sub(b, c);

let expected = f32x4::from([-7.0, -10.0, -13.0, -16.0]);
assert_eq!(result, expected);
